Objective In order to observe the effect of recombinant human granulocyte/macrophage colony-stimulating factor (rhGM-CSF) gel for external use on animal model of burn. Methods rhGM-CSF gel for external use was prepared, and its quality control and stability at different temperatures were investigated extensively based on methods describe in China Pharmacopeia (Edition 2005), including appearance,...
Based on TM remote sensing images in 1989, 2000 and 2008, combining with GIS technology, and the city of Beijing's land use change characteristics in the past 20 years from 2008 will be analyzed. The indicators such as single land use dynamics, land utilization classification index and land use transfer matrix will be used to reveal the changes on range, speed and direction of this study area. On...
Analyzing the ecological benefits from different land utilization ways comparatively, by means of the evaluation of ecological service value, set a strong fulcrum for choosing rational land utilization way, and became the key point in land use pattern at present, especially in local scale. Therefore, by taking Shapingba district of Chongqing city as an example and rectifying the coefficient of ecological...
The surrounding area of the Bohai Bay has one of the highest economic development rates of China. Rapid industrialization and urbanization has resulted in extensive changes in land use, including the construction of harbors and embankments. For the analysis of the changes of the coastlines, multi-temporal Landsat images have been used, in combination with topographical and nautical data. From the...
Persistent Organic Pollutants (POPs) mainly cause harm to the reproductive function of human being and animal kingdom, which is a serious threat to human and animal survival or reproduction. This paper blacklisted 70 kinds of POPs and outlined their character and pollution hazards. Therefore, China should strengthen basic research in POPs pollution, strengthen the environmental management and the...
With the development of society and technology, human beings on the natural environment sphere of influence and strength are constantly increasing. It causes more and more regional ecological environment problems. To protect and improve the ecological environment has become the major issues which the most world countries and areas paid more and more attention to. Ecological sensitivity analysis is...
Comprehensive study about the development of the precipitation and runoff in Li River was taken by using such methods: regression analysis method, Mann-Kendall rank correlation test method, sequential clustering method and mean value test method. Further the influence caused by the environmental change in the upstream of the Li River to runoff was analyzed. According to the results, the trend lines...
Based on the transition probability calculated by the transition rate of land use and land cover change (LUCC) area, the simulated LUCC area almost equal to the actual by Markov chain model in Tibetan Plateau. It shows that Markov chain model can be used to simulate the land use and land cover change of Tibetan Plateau. From the results of simulated LUCC of Tibetan Plateau in the next 20 to 40 years...
The ecological socialism is an important 1socialism ideological trend and faction deriving from ecology movement in the west in 1970s. It contains many valuable thoughts,theories and viewpoints, which have the significant enlightenment function in constructing the socialist harmonious society at present. Constructing the socialist harmonious society should stick to the socialist road: should follow...
The disinfection efficiency of Cl2 and ClO2 on water purification was compared. The result showed that with the same dosage, ClO2 had better bactericidal efficiency than Cl2 and produced less trihalomethane compounds than Cl2. ClO2 disinfection has the advantages of high efficiency and safety in use. ClO2 was suggested as a new disinfectant in supply water treatment.
The deterioration of traditional environmental problems has threaten the human security in worldwide and the environmental security has come into being. Inrecent research status of environmental security, the authors put a new research concept that researching the environmental security problems in perspective of macro-security. Environmental security, considered as one of the important branches of...
Through the investigation of HRMIS in Poyang Lake Ecological Economic Zone, this paper analyses the principle of designing, the path of development, the functional structure, the implementing measures, and its application prospect, and then put forward the suggestion about the outline of the construction of HRMIS in Poyang Lake Ecological Economic Zone.
land use is the main human disturbance to accelerate the soil erosion. According to the land use types of the Hengduan mountainous region in the Eastern Tibet, this paper discussed the influence of the land use on the soil erosion type, erosion intensity and erosion spatial distribution. It indicated that the soil erosion types changed accordingly with land use changes. Freeze-thaw erosion and water...
Water resource security is a globally environmental problem. This study examines three stages through which the rivers and lakes in Jianghan Plain has gone. 1) Before Holocene, merely affected by climate and Geologic structures, the lake water and river water exchanged freely. 2) In early and middle Holocene, water exchange between the lakes and rivers remained unrestrained, but the minor impact from...
This article is based on the realistic environment foundation of our country current city sculpture construction. Take the entire urban internal sculpture as object for study, unify the present situation of our country city sculpture construction development, summary some promiscuous phenomena and erroneous zone guidance which exist the current city sculpture construction and plan, through the analysis...
The protective exploitation of marine cultural landscapes is important part of cultural industry system of Zhejiang province. Base on analysis of Present Situation of Protection, Development and Utilization of marine cultural landscapes in Zhejiang province, the paper advanced Connotation of protective exploitation of marine cultural landscapes in Zhejiang province. The exploitation practice in Zhejiang...
Marine cultural landscape is one of the important types of the new world heritage- cultural landscapes. Based on the Classification methods of cultural landscapes, considering the spatio-temporal character and regional features of marine historical cultural, marine cultural landscapes were classified 6 types. It included relics and ruins landscape, Historic site landscape, Historic vernacular landscape,...
Geomorphical environment is the most important natural factors on the formation of ocean cultural landscape. It directly impacts on solar radiation, material sources and other natural elements, and it has also affected the frequency, intensity and spatial pattern of human activity. Through analyzing the adoption of geomorphical environment on the formation of coastal cultural resources, the author...
The post-disaster reconstruction should be combined with Human inhabitation and settlement environment construction, which can achieve sustainable development strategy, promote economic growth, make the social development be harmonious with the environmental protection. The post-disaster reconstruction of Longan town, Pingwu County in Sichuan province has combined supporting systems of infrastructure,...
Based on RS, GIS and statistical analysis, this paper discusses the relationship of rural settlement spatial distribution and topography, landform, soil erosion, economic development, as well as achieves the classification of population pressure in Huanren County in Eastean Mountain Areas. The results show that the distribution pattern of rural settlement is affected obviously by elevation, slope,...
